CHARLES R. YVHITTIER, OF YONKERS, NEW YORK.

HYDRAULIC ENGINE.

SPHGIPICATION forming part of Letters Patent No. 341,198, dated May 4, 1886.

Application filed February 5, 1886. Serial No. 190,938. (No model.)

To all whom it may concern:

Be it known that I, CHARLES R. WHITTIER, of Yonkers, in the county of \Vestchestcr and State of New York, have invented a new and Improved Hydraulic Engine, of which the following is a full, clear, and exact description.

lliy invention relates to that class of hydraulic engines wherein the piston is stationary and the cylinder is caused to reciprocate by the inflow and discharge of water; and the invention consists of the construction, arrangement, and combination of parts, all as here inafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification,in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a sectional elevation of my new and improved hydraulic engine, and Fl 2 is a side elevation of the same.

A B represent two parallel columns, preferably hollow. The cylinder 0 is placed between the columns A B, so that they serve as guides or ways for the reciprocating movement of the cylinder, the same being connected to the columns by the apertured flanges a c, or by other suitable means. The pistonhead D is held stationary upon the arm E, which is by preference hollow for the passage of water to and from the cylinder 0, and the arm E is by preference connected with the hollow column A, which serves as an induc tion and eduction pipe; but a separate induction and eduction pipe may be used, if de sired, in which case the column A and arm E may be made solid.

F represents the stationary multiplying sheaves, which are jourua-led on the shaft f, held in the uprights f f, secured to the upper ends of the columns A B, and G represents the movable multiplying sheaves journaled upon the shaft held in the arms 9 at tached to the lower head-plate of the cylinder 0, so as to move with the cylinder. The hoisting-rope H passes over the multiplying sheaves F G in the ordinary manner, as shown in dotted lines in Fig. 2, so that the weight uponthe rope tends to elevate the cylinder C,

and thus the cylinder 0,- the water contained therein, if any, and the sheaves G, act as counter-weights to any load or weight upon the hoisting rope H. The valve J being turned to connect pipes b c, the weight upon the hoisting-rope II will elevate the cylinder 0 and force the water therein through the hollow piston-rod E, hollow column A, and said pipes 0 I),- but the valve J, being reversed to connect the supply-pipe c and pipe I), water will enter the cylinder 0 through hollow column -A and hollow piston-rod E and force the cylinder 0 downward away from the piston-head D, causing the rope H to hoist its load. Any water that may escape past the piston-head I) will be conducted off through the hollow column B, the water being conducted to a small hole, (2, in the column by a shallow groove, 0, made in the upper surface of the cylinder 0, as shown in Fig. 1.

\Vith this engine only small counterbalanceweights are required, and the cylinder may be made comparatively short, so that no equalizing-pipe to equalize the pressure of water in the cylinder is required. The engine is also comparatively cheap to construct and effective in action, and in case any air collects in the cylinder it precedes the water in leaving the cylinder, so there will be no sudden drop ping of the load on the hoisting-rope when the water is completely exhausted from the cylinder 0.

Having thus described my invention, what I claim'as new, and desire to .secure by Letters Patent, is-

l. The hollow column A, connected to the hollow stationary piston-rod E, in combination with the stationary piston-head D and the movable cylinder 0, guided by vertical ways and carrying multiplying pulleys G, which move with the cylinder, substantially as and for the purposes set forth.

2. The combination, with the movable cylinder (land stationary piston I), of the hollow columns A B, that form guides for the cylinder and conduits for water, substantially as described.
